Hello, > >echo "10de 0264" > /sys/bus/pci/drivers/nForce2_smbus/new_id You may also try to change it in your kernel if you are able to recompile it on your own. Just go to the linux/drivers/i2c/busses/i2c-nforce2.c Find this line: { PCI_DEVICE(PCI_VENDOR_ID_NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP04_SMBUS) }, And change it: { PCI_DEVICE(PCI_VENDOR_ID_NVIDIA, 0x264) }, Delete the .o and .ko files and recompile whole kernel. See if it helps. Also watch the kernel log if there is new message. We can have more clue from the DSDT acpi table because it seems you have the special asus ATK0110 virtual device that might handle the bus and sensors. Please provide the output of cat /proc/acpi/dsdt > dsdt.bin and send it to me in private (because mailing list do not like binary attach or put it online somewhere) Thanks, Regards Rudolf
